I'm struggling to understand the compatibility of the MimbleWimble backbone + unlimited supply:
For a potential "everyday use" cryptocurrency that dominates the global economy, I think some rate of inflation/emission is 100% necessary.
But I don't think Grin is trying to be that with the way everything else is situated. The elimination of denominations and addresses makes this currency fundamentally difficult to interact with. I also think an inherently private coin would be incompatible with the role of worldwide day-to-day use.
I don't see any other situation for Grin or any crypto where unlimited supply is a good thing to have. What's the justification?
I don't think they want people to speculate and hoard this currency. I think they want to avoid the criticisms of bitcoin being all held in massive amounts by early adopters. They want it to be for spending and pricing, for real world use. It probably will be more stable than other cryptos in a few years. Perhaps just gradually decreasing in value a little bit every year for the foreseeable future.
As for it being too hard to use, well yes it certainly is right now, but I mean
Of course it's going to be rough. There is no reason why it can't progress in an ever more user friendly direction from here moving forward. It could be pretty easy. Imagine if grin in the future had a built in DHT. There would be no need to configure anything, as long as your wallet was running it could receive. And a company that owed you payment could ping you every few minutes for as long as it took at trivial cost. And the ability to send funds through email could actually be really convenient when it's not so rough around the edges. I'm thinking drag and drop from email or other source into the wallet and done.
We will see. I'm here because this is something real. It's not a get rich quick hype coin. It's real, new, innovative technology. We only see that every few years in this space if we are lucky. I will always come back to be a part of it every time it turns up. And I expect I will see a lot of the cool familiar faces here or elsewhere when I do, time and time again.
